When you're not using things, unplug it. Most appliances pull energy, even when they're turned off. It's called vampire power. Some sources it can cost a household as much as several hundred dollars a year. It's easy to unplug things like lamps, chargers, computers, electric toothbrushes and such. I don't unplug our main TV or DVR box so as to not interfere with my precious, precious recordings, but every little bit helps.
